Gents.

One of my rear wheels (thats right, only one) is scrubbing on the guard when i've got people in the back seat.

I figure that it doesnt happen on the other side because it must have very slightly more negative camber.

Is it possible to adjust the rear camber at home, and if so, any tips?

Thanks in advance.

And before you suggest I head out to get a wheel alignment, im just after a quick temporary fix. Wheel alignment is coming soon along with new tyres.

don't do it at home... just stop putting people in the back, put them on the good side!

Check tyre pressures...

Think laterally. Is it really the camber, maybe it is a soft shock, shorter spring, the camber of the road, the weight of the people in the back and is it really the tyre and not some other noise.

Thanks Stephen.

It doesnt matter which side the people sit in. A "large" passenger in the front seat has the same effect.

Tyre pressures are OK.

Springs are the same on both side (aftermarket RSR Ti2000). Shocks are nismo s-tune. Both appear fine.

The scraping doesnt occur when I run the standard 18s. These 20"s are in a much more agressive offset.

The RHS appears that it could JUST BARELY tuck under the guard over bumps, where as the LHS looks like there is no chance. This is why I think I can dial in a tiny bit more neg camber on the LHS and it will be OK.

fender rolling is the only wat. what is your size on you wheels? the width play effect too. mine is 10.5 rear with 22+ offset and 275 tyre scrub with passenger as well. fix the scrubbing by fender rolling.

Perhaps your diff and rear axle (bushes) are kicked to one side slightly.

Should be absolutely central unless it has taken a knock. Would still suggest that you take it to a professional. Maybe you could take some measurements first and see how much it is.

Use some straight edges on the face of the wheel and see where the guard sits...

Seems very odd, unless something is installed incorrectly.

If there is 'No Chance' that the wheel will clear on the left, I would have thought you will not get enough adjustment by just negative camber adjustment. Not sure you can use much more than 1 degree negative and it is a dangerous not doing it correctly.

Pick up a copy of High Performance Imports Issue 110 (High Performance) and take a look in the handling pages.

The maximum -camber is not a large figure

Thanks.

Rears are 20x9.5 +22, wearing 275/30.

There is JUST enough room to get away with not rolling the guards. However, my plan is to eventually get it done once I fork out for some better rubber (and run less agressive camber).

Stephen, thanks again for the additional ideas.

I dont want to sound stubborn but it really is a camber issue.

I tried to take a photo of the underside of the guard but my photographing skills are sub-par. Once you see the black mark left by the tyre and how close it is to fitting underneath, it will make a lot more sense.

I dont have a protractor (ha ha) but it looks like even 0.5 of a degree may be all it will take.

In any case, with some help I discovered how to adjust the camber but we could not get enough leverage on the bolt. Will get it done tomorrow and report back.

I'm running 20 x 10.5 + 22 w/- 285's on the rear. Ive got stock camber, had the guards rolled slightly and no rubbing. There is no camber adjustment without going aftermarket and I can't see that being your problem. You must have a rear end alignment problem. Might be worth taking to a pro who can diagnose the issue and possibly fix it.

I was going to ask if it was the left side rubbing when you take right hand turns, as the turn you take is a bigger arc, higher speed, weight shifts over a bit more..

The RHS appears that it could JUST BARELY tuck under the guard over bumps, where as the LHS looks like there is no chance. This is why I think I can dial in a tiny bit more neg camber on the LHS and it will be OK.

... but I guess not.

I agree completely, especially with the idea that there is "no camber adjustment without going aftermarket".

Unless you have something different, most Nissan's do not have Camber adjustment as standard... I'll stand corrected but that is front or rear from my knowledge.

They do actually but only to a very minimal degree. I had a wheel allignment done on my 35 months ago and rear cambers were corrected slightly. I Also remember my R34 had a little bit of camber correction done as well. It is very marginal but there is a small degree in there. Failing which most people get camber kits. I would not recommend you play with those adjustments but rather get it to a wheel allignment specialist.

Easy fix would be to roll the inner lip.

I personal gripe of mine is when people post incorrect info on public forums.

Camber IS adjustable on the rears from factory (via the eccentric bolt on the camber arms). The scope of adjustment is minimal but it is there. Toe can also be adjusted via the toe arm.

The fronts are another story.

Thread can be closed, my problem is solved. Thanks for listening.

The info was correct sir. The camber bolt is a very marginal adjustment and has no effect on any suspension arm angle other than stock. There certainly would not be enough adjustment on a lowered vehicle.

when you say "not enough adjustment" for a lowered vehicle, how many degrees / minutes can the stock camber bolt change camber?? +/-

Most cars I know of dont really have excessive camber changes even when slammed...usually aftermarket options are a last resort to actually dial more negative camber than what the factory bolt will allow.

The info was correct sir. The eccentric camber bolt has a very marginal adjustment and does not have enough "range" in order to return camber to stock with a lowered suspension.

edited to be more specific.

I was able to get the morning off work.

Stopped by the tyre factory. Surprise surprise, camber on the LHS was -0.5 something, RHS was -1.4 something.

A quick adjustment and the problem was FIXED. -1.5 or there abouts on both sides now and no scrubbing.

Cool, that was exactly what mine was corrected to -1.5 after I lowered it on 350z suspension.

The lower you go the more natural camber you will have.

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Thanks for all that information I appreciate it. To answer your questions: - Yep that's what I mean. These guys are professional painters to so I must be missing something. It's a bit hard to explain. - With the primer landing on clearcoat, I make sure that the surrounding clearcoat is scuffed to 240 grit as my epoxy primer says that I only need to sand the area to 240 grit. - Yeah so similar to the first question, assuming that the paint landed on the unscuffed clearcoat because I've seen that happen. - Yep I want to prep the surface in that order. Only reason because epoxy primer will protect it from rust and I need that atm with this crappy Sydney weather. I think I was worried about time, if I try to put the filler down but screw it up somehow and I don't have time to sand it off and reapply it then need to put primer later that it might start to rust again so I wanted to apply the primer as quick as possible to not deal with rust.  - My car has heaps of small dents, that definitely need filler but are you also sanding the area to 240 grit to fill it in with filler? I always thought you have to go to bare metal for filler to stick but that contradicts the point then that you can put filler on epoxy primer.  If you aren't going to bare metal, AND not putting epoxy primer how are you making the dent stick to the paint?

      Did tie rods. Steering now not "springing" back.

      I did. I went to a suspension guy and he told me because I don't have adjustable camber arms it's the reason why my car veers towards the left if I take my hands off the wheel but if I drive my other every day car and take my hands off the steering wheel it goes completely straight. I think it's common with Skyline's. In order to fix the problem, I likely need gktech camber arms then nismo bushes since I have poly bushes atm, then a wheel alignment after that. With my car if I take my hands off the steering wheel on a really bumpy road before stopping at a light I have to hold my steering wheel somewhat tight otherwise my car will legit just go completely in the other direction quite quickly and I'll slam into something lol instead of stopping straight. I Believe this YouTuber had the same issue and fixed it with gktech arms. At timestmap 6:05 he talks about how the car doesn't veer anymore after installing these arms.

      BCNR33 Blower Motor Resistor - Testing

      By itsforandres · Posted

      hello! does anyone have a schematic that shows how to test the blower motor resistor for the vac system? i believe the part# is 27761-15U00. I think the resistor is toast, but would like to be able to test it somehow before i embark on the journey to find a new one. cheers! 27761-15U00

      R33 general questions

      By soviet_merlin · Posted

      I don't know the answer to this, but did you have a look at the parts diagrams on amayama.com and see what they list around it for your car? As an example this should be it on my car. That's how I would check for required clips and things like that. But, I take no responsibility for you ending up with a box full of random OEM hoses, washers and clips after going down that path a few times. This definitely has never happened to me

      Most driving should* be done on one side of single lane divided roads. In the RHD world, you drive on the left side of the dividing line and the road is probably cambered equally on both sides. So your side of the road slopes away to the left. The same is true for the LHD world, just everything swapped to the other side and opposite slope. With a perfectly neutral, straight ahead wheel alignment designed to drive straight on a perfectly flat surface (or at least one that is level on the left-right axis, even if it has some slope in the fore-aft axis) you will not be able to drive on a cambered road without the car wanting to drift down the camber. You will need to add steering input in the opposite direction all the time. This is annoying. The solution has always been to set the camber and/or the caster to produce a continuous turning force in the opposite direction of the camber. The car will drive straight on the kind of camber for which it was set up, presumably as described in the top paragraph. But.... when the car is set up this way, as soon as you get into a lane, usually on a multi-lane surface road or highway, where the camber is not as presumed during setup, the car will usually pull to one side. In the RHD world, if you are in the fast lane on a big divided road, you are probably on the opposite camber compared to what the car was set up for (ie, sloping down to the right) and the combination of the setup and that camber will make the car want to go right pretty hard. Even a perfectly flat lane will tend to want to go right. There's no getting around it. Civil engineers who know their stuff (which is not an assumption that can always be made) will attempt to keep the variation in camber across a multi-lane road as small as possible, and if they can will attempt to make the fast lane as close to flat, or even cambered in the same direction as all the other lanes. This takes a lot of planning for drainage, control of levels, ability to deal with the elevation changes that occur at road junctions, etc etc. So it's not trivial to get it right. When they do make it work, then the annoyance is reduced, along with tyre wear, fuel consumption, etc. In theory, the civil engineers are supposed to worry about those aspects of road design also. * This used to be true, but now with very large highway systems, even just multi-lane surface roads running everywhere, it is less true now than it was, but the old assumption is the basis for describing the phenomenon, so let's just run with it for the moment.
